Neonatal hyperthyroidism is a rare,transient,but serious disease,while it can lead to significant morbidity and mortality if without prompt diagnosis and adequate treatment.Most cases are secondary to maternal autoimmune hyperthyroidism (85％ ～95％ are Graves'disease),caused by transplacental passage of maternal stimulating TAHR anti-bodies (TRAb).Signs and symptoms are multifaceted,nonspecific,and it can be easily confused with sepsis and congenital viral infections.The management of pregnant women with thyroid diseases during pregnancy should be strengthened.It is recommended to monitor thyroid function and TR-Ab levels from the beginning of 20 weeks'gestation.Neonates with symptomatic hyperthyroidism require prompt initiation of therapy and close monitoring of response in consultation with a pediatric endocrinologist.Here we will review the latest research progress in pathogeneses,clinical manifestation,diagnosis and treatment of neonatal hyperthyroidism.

BACKGROUND: Time to first cigarette after waking is an indicator of nicotine dependence. We aimed to identify the association between time to first cigarette and spirometry-proven obstructive respiratory impairment, especially chronic obstructive pulmonary disease, in current smokers. METHODS: We included 392 subjects who visited the comprehensive medical examination center of Hallym University Sacred Heart Hospital between July 2014 and September 2015. Subjects with lung disease or anemia were excluded. Obstructive pulmonary impairment was defined as < 70% of the predicted value of forced expiratory volume in 1 second/forced vital capacity. Subjects were classified into the early (≤30 minutes) and late (>30 minutes) groups based on the time to first cigarette. Logistic regression and linear regression analyses were used for data analysis. RESULTS: Ninety-eight subjects (25%) were classified into the early group. After adjusting for smoking behaviors (cigarettes per day and smoking duration), socioeconomic status (education and income), age, and physical activity, an early time to first cigarette was found to be associated with an increased risk of obstructive pulmonary impairment measured using spirometry (adjusted odds ratio, 2.84; 95% confidence interval, 1.22–6.61). CONCLUSION: Compared to current smokers with a late time to first cigarette, those with an early time to first cigarette had a higher risk of obstructive pulmonary impairment, especially chronic obstructive pulmonary disease. Classifying smoking-related behaviors, especially time to first cigarette, may help target clinical screening for chronic obstructive pulmonary disease.

Objective: To explore the effectiveness and cost of breast cancer screening strategy that is suitable for the current econom-ic conditions in China. Methods: We collected clinical and cost information of breast cancer screening for Chinese women based on previous screening programs conducted from February 2008 to December 2011 and collected the same information about breast can-cer cases diagnosed in hospitals at the same time. Markov models were developed to analyze the incremental cost-effectiveness ratios (ICER) for 132 breast cancer screening strategies compared to no screening for Chinese women. Results: In 2010, as compared to no screening, the most cost-effective breast cancer screening strategy was biennial screening with clinical breast examination (CBE) and breast ultrasound, in parallel, for women aged between 40 to 64. This screening strategy could save 1,394 quality-adjusted life years (QALY) per 100,000 women, and the cost of saving breast-cancer related QALY would be 91,944 RMB. Sensitivity analysis indicated that in 2016, the most cost-effective breast cancer screening strategy was biennial screening with CBE and mammography (MAM), in parallel, for women aged 40 to 64, with ICER of 159,637 RMB per QALY. Conclusions: Population-based breast cancer screening would be acceptable in the current conditions in China. As the Chinese economy and level of medical care improve, breast cancer screening would be more cost-effective.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.
